It supersedes the previous editions published in 1982 and 1970 under the title Three-P
42、hase Network Transformers.This Standard includes updated electrical and mechanical requirements that reflect current practice. Transformer enclosure finish is one of the key areas that have been updated.This Standard was prepared by the Subcommittee on Network and Submersible Distribution Transforme
43、rs, under the jurisdiction of the Technical Committee on Distribution Transformers and the Strategic Steering Committee on Power Engineering and Electromagnetic Compatibility, and has been formally approved by the Technical Committee.June 2008Notes: (1) Use of the singular does not exclude the plura
44、l (and vice versa) when the sense allows.(2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.(3) This publication was devel
45、oped by consensus, which is defined by CSA Policy governing standardization Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in
46、the Technical Committee list and yet not be in full agreement with all clauses of this publication.(4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee.(5) All enquiries regarding this Standard, including requests for i
47、nterpretation, should be addressed to Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6. Requests for interpretation should(a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;(b) prov
48、ide an explanation of circumstances surrounding the actual field condition; and(c) be phrased where possible to permit a specific “yes” or “no” answer.Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSAs peri
